Abstract

The paper examines the hypothesis of unit roots in interest rates [Proxied by Treasury bill-T-bill- rates (91-day T-bill rate, 182-day T-bill rate, and 1-year T-bill rate] for Ghana for the period 2007 to 2013, using monthly data. The test was performed by employing the Augmented Dickey-Fuller (ADF) test and the Kwiatkwski, Phillips, Schmidt and shin (KPSS). The results of the tests indicate T-bill rates have unit root in levels supporting the unit root hypothesis for Ghana.
